Sub vibrates when stereo turned off
I need some help i just recently installed a sub and amp into my ranger and when I turn the stereo off the sub begins to vibrate like its getting feedback
I have a 2008 ranger with stock deck, I spliced a line output converter into the rear speaker inorder to get my RCA's for the amp, ran the power wire to battery and the remote trigger to the fuse panel.
Any ideas what might be causing the sub to vibrate when the stereo is off?
thanks in advance
